III llll 1E ST GEORGE D. GRIFFICE, OF BIG SPRING, TEXAS.

CULTIVA'IOR.

To all whom it may concern:

Be it known that I, GEORGE D. GRIrFIcE, a citizen of the United States,residing at Big Spring, in the county of Howardand State of Texas, haveinvented certain new and useful Improvements in Cultivators, of whichthe following is a specification, reference being had to theaccompanying draw- 1ngs.

This invention relates to certain improvements in cultivators and it isan object of the invention to provide novel and im proved means wherebya cultivator of con ventional construction may be readily andconveniently converted into a surface cultivator. i

It is also an object of the invention t provide a novel and improvedattachment for a cultivator whereby an ordinary cultivator may beemployed as a surface culti vator and wherein the cutting'bladeiseffectively held against displacement after the attachment has beenapplied to a beam. The invention also has for an object to provide noveland improved means whereby the beams of a cultivator may be effectivelyheld against relative or lateral displacement.

The invention consists in the details of construction and inthecombination and an rangement of the several parts of myim provedcultivator whereby certain important advantages are attained and thedevice is rendered simpler, less expensive and otherwise more convenientand advantageous for use, all as will be hereinafter more fully setforth.

The novel features of the invention will hereinafter be definitelyclaimed.

In order that my invention may be the betcompanying drawings, whereinFigure 1 is a view partly in elevation and partly in sectionillustratlng an attachment constructed in accordance with an embodi-'ment of my invention and in applied position' V Fig. 2 is a view in sideelevation'of the attachment as herein embodied, the coacting beam of acultivator being shown in fragment;

Fig. 3 is a view in top plan of the device as disclosed in Fig. 1;

Specification of Letters Patent.

Patented Aug. 21, 1917.

Application filed October 16, 1916. Serial No. 125,909.

Fig. 4 is a sectional view taken substantially on the line 44 of Fig. 2;

Fig. 5 is a fragmentary view partly in elevation and partly in sectionillustrating a slightly modified form of invention;

Fig. 6 is a fragmentary view in elevation illustrating a still furthermodified e1nbodiment of my invention; and

Fig. 7 is a fragmentary view in end ele-.

vation of the device as disclosed in Fig. 6.

As disclosed in Figs. 1 to 3 of the accompanying drawings, B denotecultivator side beams of conventional construction and with each ofwhich is operatively engaged a casting C for suitablysecuring to saidbeam B the shank S of a conventional cultivator plow and which plow isomitted in the accompanying drawings. I

Tdenotes a table preferably rectangular in top plan and which isprovided with the depending split barrel 1 through which the beam B isdisposed and coacting withthe barrel 1 and the table T are the clampingmembers 2 of conventional'type and which serve to effectively hold thetable T to the beam B, as is thought to be clearly apparent to thoseskilled in the art to which my invention appertains, and as isparticularly illustrated in Figs. Q'and 3, the table T is positioned inpredetermined spaced relation relative to the casting C. It is notessential however that the table T and the barrel 1 be integrallyconnected as the table may be separate as'is disclosed in Fig. 5 of theaccompanying drawings and wherein the table T is independent of thecasting or barrel 1* but is eflectively held thereto through the mediumof the clamping mem ber 2 Integrally connected with the barrel 1 is asecond barrel 3 arranged at substantially right angles to the barrel 1and table T. and through which is adapted to be directed thesupplemental shank S.

An intermediate portion of the barrel 3 is enlarged, as at 4, and withinsaid enlarged portion 4 is positioned the eye member 5 through which theshank S is directed, and said eye is provided with the radially disposedthreaded shank 6 extending exteriorly of the barrel 3 or moreparticularly the enlarged portion 4 thereof and has coacting with itsextended portion the clamping nut 7 whereby it will be perceived thatthe shank S may be effectively held in a predetermined longitudinaladjustment.

The upper end portion of the shank S, as indicated at 8, isangular incross section and is adapted to be disclosed through an opening 9 ofcorresponding configuration produced in one end portion of the link orbar 10; The opposite end portion of said link or bar 10 is provided withan opening 12 through which is adapted to be extended the upper portionof the shank S. With the link or bar 10 in applied position it will beperceived that the shank S. is effectively held against any rotarymovement.

The outer side portion of each of the tables T or T is provided with anopening 14 through which is extended the threaded shank 15 dependingfrom the spreader or hobble 16 which is adapted to be connected, as at17, with thespreader or hobble extending from a second beam B, andwhereby said beams are effectively maintained against relative lateralmovement. The shank 15' has coacting therewith the clamping nut 18whereby it will be perceived that the hobble or spreader 16 iseffectively held to the table T or T. v

In order to maintain the link or bar 10 against displacement, it ispreferred to insert through the portion 8 of the shank S at a pointabove the bar or link 10 a c'otter pin 19 or the like. v

The lower ends of the shanks S and S coacting with a common beam B areconnected by the ground engaging member or plate 20 through the mediumof the removable bolts 21, said plate 20 having its flat facesvertically disposed and having its lower or engaging edge disposedparallelto the ground being worked. I I

To the outer faces of each of the plates 20 is secured a substantiallyfiat blade 22, said blade 22 being disposed r'earwardly and outwardly ona predetermined incline and having its inner end provided with anupturned portion 23 overlying the outer face ofthe plate 20 and it is tobe noted that the removable bolt 27 serves as a means for securing saidblade to the plate. The blade22is also further secured to the plate 20as indicated at 28.

It is also to' be noted: that the connection between the blade 22 andthe plate 20 is, adj acent the forward end of said plate and coacts withthe forward shank S.

Secured to the inner face of the plate 20 adjacent the rear of saidplate is a sec-- ond substantially flatbla'de 24 disposed inwardly andrearwardly on a predetermined incline and having its inner endpr'ovide'dwith an upstanding extension 25 through less than the blades 22 andserve to coact with the soil immediately adjacent the opposite sides ofa plant row.

As illustrated in Figs. 6 and 7 a plate 2O substantially square in formis adapted to be secured, at 21, to one of the shanks and preferably theshank S, and secured to the opposite sides of said 26* as indicated at26 are the blades QQeand 24*, said blades being of differing lengths anddisposed on prede termine'd inclines as has hereinbef'ore been set forthrelative to the blades 22 and 24. It is also to be observed that thesecuring eans 26 are common to both of the blades 22 and 24.

From the foregoing description, it is thought to be obvious that acultivator con-- structed in accordance'with my invention is of anextremely simple and comparatively inexpensive nature and isparticularly well adapted for use by reason of the convenience andfacility with which it may be assembled, and it will also be obviousthat my invention is susceptible of some change and modificationwithout'material departure from the principles and spirit thereof andfor this reason 1 do not wish'to be understood as limiting myself to theprecise an rangement and formation of the several parts herein shown incarrying out my invention in practice, except as hereinafter claimed.

I claim:

In combination with a beam of a culti;

vator, a plurality of shanks depending from said beam and spacedlongitudinally thereof, the upper extremity of one of said shanks beingangnlar' in cross section, a link provided with openings to receivetheupper portions of the shanks, the'opening through which the angularportion of the last named shank is directed being of-substantially thesame configuration as the cross section of said upper portion of theshank, meansdemummy disposed through the second shank.

above the link when'the link is in applied position for holding the,link against displacement, and a groundworking member connected to thelower end portion of either orboth of the shanks. V

, In testimony whereof I-hereunto afliX my signature'in the presence oftwo witnesses.
